Fanart in music problem in Alaska

I'm having an issue with fanart in my Music. In most cases when I add a new album, etc, its pulling fanart correctly. In some cases, I'm getting fanart that doesnt even match at all. For example, for one of my Beatles albums it pulled fanart of Metallica. I have a file within my main Beatles folder called "fanart" that I thought it would grab but it didnt since it already pulled that Metallica one.

The only way I have gotten this to work, only part of the time, is to remove the main folder of the artist, open up XBMC, let it scan then close it. The move the folder back and reopen XBMC, it then rescans and hopefully puts the correct fanart file as the background.

There has got to be a better way to do this and if there is, can anyone please help!
